WHEEL-HUB AND BOX THEREFOR.

SPECIFICATION forming part of Letters Patent No. 676,856, dated June 18,1901. Application tiled October 9,1900. Serial No. 32,500. (No model.)

To ctZZ whom it may concern,.-

Be it known that 1, ERNEST HENRY WAGE- NER, a citizen of the UnitedStates, residing at Modesto, county of Stanislaus, State of California,have invented an Improvement in Vheel-Hubs and Boxes Therefor; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to improvements in It is especially adapted to thatclass of plows known as the Stockton gang-plow, in which a triangularframe is mounted upon three wheels and is adapted to travel with itsshorter base in front, while the plows are carried by standards fixed tothe dagonalbeam of the frame, so that each plow in the gang successivelyturns its furrow when the machine is moved over the ground to be plowed.In this class 2o of plows the wheel-journals are subjected to a greatdeal of dirt, which rapidly wears them out and makes it necessary toreplace them from time to time.

It is the object of my invention, first, to protect these bearings andthe movable joints from as much of the dirt as possible, and, secondly,to provide a take-up mechanism by which the bearing-box is removablyfitted into any wheel-hub and is adjustable therein 3o to preventlooseness and lost motion.

4.o the hub and sleeve.

My invention therefore comprises details of construction, which will bemore fully explained by reference to the accompanying drawings, inwhich- Figure 1 is a perspective view of a gangplow embodying myinvention. Fig. 2 is a longitudinal section through the hub of one wheelembodying the main features of my improvement. Fig. 3 is a perspectiveview of Fig. 4 is a view of the hub; Fig. 5, an outer view of the same.Fig. 6 is a plan of the hub-box. Fig. 7 represents end views of theouter and inner dust-protecting sleeves. Fig. S is an elevation of thecrankarm and sleeve.

5o the hypotenuse of the triangle, carries the plows 2,01? which theremay be five or any other suitable or desired number, depending upon thesize of the plow. This plow is carried upon bearing-wheels suitablyjournaled at or near the angles of the frame, and one of these wheels isswiveled and turnable to guide the plow. The wheel 3, which is carriedat the junction of the front beam with the diagonal or plow beam of theframe, is here employed to illustrate one part of my improvement. Thiswheel is carried upon an axle or spindle 4, the inner end of which issecured to the overlapping meeting ends of the iron braces 5, the upperends of which are clamped to the front end of the frame thus shown.

The hub 6 of the wheel 3 has a tapering opening through it of sufficientdiameter to receive the box 7, which fits into this tapering opening andis adjustably locked therein, as follows: Upon the end of the hub 6contiguous to the smaller end of the tapering opening are formedinclines 8. Upon the corresponding end of the box 7 are formed beveledlugs 9, corresponding in position with the inclines 8. AThrough the hubare made slots or channels 10 of such size that when the box 7 isinserted into the hub the lugs 9 being in line with these slots 1() willpass through them, and when the box has been pushed through the hubuntil the lugs 9 have passed beyond it, by turning the box in the hubthe lugs 9 will engage the incline or beveled ends 8, and will thus actto draw the box into the hub and lock it firmly in place. In order toeffect this locking, the hub of the Wheel has a lug 11 projectingradially from its iianged portion, and the box carries a correspondinglug 12. Through the lugs 11 and 12 holes are made, and a bolt 13, ispassed through these holes, and by the head of the bolt tting againstthe surface of one of the lugs, while a nut 14 being turned upon thescrew-threaded end of the bolt against the other lug will act to drawthe two lugs toward each other, thus turning the box within the hub andcausing the lugs 9 to travel up the inclines 8 as much as may benecessary to lock the parts firmly together by forcing the box fartherinto the hub.

If by use and wear the box becomes slightly loose within the hub, a turnor two on the nut SeA pss.

14 will draw the lugs 11 and 12 a little nearer together, and thusturning the box Within the hub will cause the lugs 9 to travel up theinclines 8 a little farther and so bind the parts firmly together.

The spindle 4 passes through a box 7, and in order to prevent theentrance of dirt into the interior of the box and the consequent wearupon the parts which would thus be caused I have shown a means forthrowing any dirt outward which may fall upon the hub of the wheel andwhich might otherwise eventually find its way into the interior of thebox, and at the same time it provides a means for firmly locking thespindle and the parts carried thereby to the supporting fram e-irons 5.The ends of the box 7 are made with enlarged chambers or sockets 15, andwithin these sockets are fitted the dust-protecting sleeves 16 and 17.These sleeves have holes through them of' sufficient diameter to receivethe spindle 4, which passes through them. The outer peripheries of theinner ends of these sleeves are made cylindricaland turnable within thechambers 15 of the box. The outer ends of the sleeves are madeconvergent outwardly, and as the cylindrical portions 16 and 17 liewithin the chambers 15 any dirt Which may fall upon the hub or theprojecting ends of the box and thence fall off onto these Vsleeves willbe thrown outward by the outward taper or convergence of the parts 18.

The spindle 4 is made cylindrical where it passes through the box. It ismade rectangular Where it passes through the inner sleeve or dust-cap17, and this dust-cap has a correspondingly-shaped opening 19, which tsthe square part of the spindle. The inner end of the spindle isscrew-threaded and passes through the supporting-irons 5 and is securelylocked thereto by means of a nut 20, which itsupon the inner end. Theouter dust-cap or sleeve 16 has slots formed in its outer end, as shownat 21, and the pin 22, which' passes through the spindle to hold thewheel in place, also passes through these slots 2l and prevents theouter sleeve or dust-cap from turning. yThe inner one being preventedfrom turning by reason of the square socket 19 titting upon the squareportion of the spindle,

it will be manifest that the Wheel and the box 7, which is securedWithin it, will turn in unison while the spindle and the dust-capsremain stationary. There is thus a tendency to throw olif any dust ordirt which is carried up by the Wheel in turning and which may fall uponthe hub and to deliver it outwardly and away from the journal or wearingparts upon which the wheel turns.

Whenever there is sullcient wear to make it necessary to change thepart-s, it is very easy to remove the Wheel by taking out the pin 22,and the dust-caps or sleevescan be separated from the box and the boxitself withdrawn from the hub and the parts renewed with little loss oftime.

`It is often customary in this class of plows to carry a seedbox, as at23, upon the p1owbeam B, and an oscillating shaft 24 passes through thebox and carries radial arms, which being moved over the concave bottomof the box serve to agitato the seed and cause it to fall through holesmade in the ,bottom of the box, so that the seed is sown and coveredsimultaneously with the plowing. The shaft 24 is bent at an angle, asshown, and is connected by a loose coupling 26 with a rod or bar 27, thelower end of which is connected with an eccentric or crank pin 28 uponthe wheel 3. lt will thus be seen that the revolutions of the wheel 3,carrying this crank or eccentric pin, will serve to reciprocate the bar27, and thus operate the seeding devices, as previously described.

In order to connect the bar 27 with the crank-pin and to prevent Wear ofthe movable parts, I have shown a sleeve 29, having an arm 30 casttherewith, with holes or slots 31, which serve to receive bolts by`which it is secured to the lower end of abar 27. This sleeve has a holethrough it of sufficient size to receive an independent box 32, and thisbox fits upon the pin 28 and forms the journal. The ends of the sleeve29 are counterbored with enlarged chambers, as shown at 33, and theouter one is of sufficient size to receive the head of the bolt or pin2S, which thus covers the end of the box 32 and prevents dirt fromgetting in, so that this `joint will remain true for a long time. Y

A slightly-projecting hub or boss is made upon the wheel 3 at the pointwhere the pin 28 connects therewith, and this hub entering the oppositeend of the sleeve 29 forms a similar protection for the inner end of thebox 32. These devices serve to protect the wearing parts from dirt andto form an easilyadjustable and replaceable mechanism at a very smallexpense. The hub and box adjustment is applicable to any wheels forwhich it may be desired to .use it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with-a vehicle, and the bearing-wheels thereof, of anindependent journal-box fitting the hub of the wheel and turnabletherein, and means including inclined surfaces on one of the parts andlugs on the other part engaging said surfaces, for locking said box inthe hub.

2. The combination in a bearing-wheel of a vehicle, of a hub having atapering hole therethrough, a box having a corresponding taper onv itsexterior adapted to fit within the hub, lugs formed uponl the box toengage inclined surfaces of the hub, and means for turning the boxwithin the hub whereby it is locked thereto.

3. The combination in the wheel of a vehicle, of a hub having a taperingopening therethrough, a journal-box having a correspondingly taperedexterior, lugs formed IIO upon the surface of the journal-box and slotsy in the hub through which said lugs may be passed, inclined surfacesupon the end of the hub= lugs fixed respectively to the Vopposite endsof the box and the hub, a screw-bolt by which they are drawn toward eachother kwhereby the box is turned in the hub and the lugs at the oppositeend are interlocked With the inclines of the hub.

' 4. The .combination in a vehiclenvheel oi' a hollow hub and removableinterlocking j ou rnal-box, said boxhaving chambers in its ends,dust-caps or sleeves titting therein, the outer ends of said caps beingtapered or convergent to throw 0E the dirt.

5. The combination in a vehicle-wheel of a hollow hub a journal-boxfitting and interlocked therewith, chambers made in the ends of the box,sleeves or dust-caps fitting in said hand.
